Recreating Atari XL / XE floppy disks

There is plenty of free software available for the 8-bit Atari XL / XE computers online in the form of ATR files. These are image files created from the physical disks. A hudge database can be found on Atari Mania website. It is possible to mount these images with an Atari XL /XE emulator like Atari800Win. AtariAge website has an extended description on how to do it. However in this blog I am going to describe how to create floppy disks from these downloaded images so they can run on a real Atari XL / XE computer with a floppy disk drive.

Commodore 64 PLA chip replacement

The most important chip in commodore 64 computer is the PLA chip. When this chip is broken, nothing will work and most certainly you will get a black screen after you try to turn it on. The original replacement chip is hard to get and if you find one it is not cheap. Luckily there are alternatives for replacement. It is possible to create one using EPROM, however the results of it's performance vary, or you can buy one on the market like SuperPLA, realPLA, U17 PLAnkton or PLAtinum.
